CAP-FERRULE FOR PAPER BOXES.'

Patented Mar. 9, 1915.

Application filed February 2, 1910. Serial No. 541,632.

To all whom it may concern Be it known that I, JERvIs R. HARBECK, a citizen of the United. States of America, yresiding at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Caplowing is a specification, reference being had therein to the accompanying drawings.

The invention relates to the manufacture of paper boxes or packages, and has more particular reference to the construction of ferrule or tip for protecting the end of the paper body, and to which the cap is secured. It is the object of the invention to provide means for securely fastening this tip or ferrule to the body and in such a manner as to permit of forming screw threads upon the errule for the engagement of a screw cap.'

To this end, the -invention consists in the construction and the method of attaching the same as hereinafter set forth.

In the drawings-Figure 1 is a perspective viewv of a portion of a paper package provided with my improved construction of tip or ferrule; Fig. 2 is an enlarged sectional 4perspective view showing the tip or ferrule before securing to the body; Fig. 3 is a plan view of the ferrule; and Fig. 4 is an enllgardged section showing it attached to the A is the paper body, and B the ferrule for protecting the end thereof. This ferrule, as shown, is formed with screw threads C, which are adapted for engagement with the screw cap (not shown). To secure this ferrule to the body, it is first formed as illustrated in Figs. 2 and 3 with the inwardlyextending flange member D- radially notched or slit at E to divide the same into a series of pointed sections F. The pointed ends G shown in Fig. 2, after which the ferrule is placed in engagement with the paper body, and the sections F are bent over to lie against the inner face of the body, the points G being embedded therein. This operation may be conveniently performed by the insertion of a punch or plunger member into the end of the body, as indicated by the dotted lines H, Fig. 4, the result being that all of the sections F are simultaneously bent, and all of lhei points G are pressed into the paper The construction described is one in which the ferrule is secured without possibility of accidental displacement, and'without injury to the threaded portion. ,y

What I claim as my invention is:

1. In a box or package, the combination of a body formed of fibrous material, and a ferrule stamped from a single piece of metal comprising a wide seamless screw-threaded portion engaging one wall of the body, a lateral portion engaging the end of the body, and a portion notched to form a plurality of spaced prongs engaging the other body wall, said 'prongs having transversely extending points embedded within the body.

2. A ferrule for paper boxes, stamped from a single piece of sheet metal, and comprising a cylindrical screw-threaded portion adapted to engage the exterior of a paperV box body, and a flange extending inwardly from the upper edge of the said cylindrical portion, said flange comprising a lateral portion adapted to engage the edge of the box JERVIS R.
